ELECTROMAGNETIC SHUTTLE-OPERATING MECHANISM.

Specification of Letters Patent.

Application filed March 18, 1913. Serial No. 755,172.

To all who) it may concern:

Be. it known that I, ERNEST L. Dr: Lose, a

citizen of the United States} residing at Plant City, in the county of Hillsborqamd State of Florida. have invented certain new and useful Improvementsin Electromagnetic Sht.utle()perating .\lerhanisni, of which the following is a specification. My invention relates to certain new and useful imprmt-nn-nts in the means for actuating the shuttles of looms, and one object of my invention i to provide a simple, cheap and highly etii ient me hanism by which the usual pi ker-sticks and th ir many coaeting parts may he. entirely dispensed with.

A further object of my invention is to provide t l"til()-llin,'llltti(f means for throwing the shuttle ttCloss the loom and also to pr0- vide means for controlling and properly timing the operation of the electromagnetic means.

\Vith the foregoing and other objects in view my invention consists in certain c0n struetions, combinations and arrangements of partsthe preferred form of which will be first described in connection with the accompanying drawings and then the invention particularly pointed outin the appended claims.

Referring to the drawings wherein the same part is designated by the same reference numerals wherever they occur, Figure 1 is a front view of a lay and its adjuncts embodying one form of my invention; Fig. 2 is a top plan view of the lay shown in Fig. 1; Fig. 3 is a \ertiral section through a well knownt'orm of loom, showing the same however as equipped with the embodiment of my inVentirm-as is shown in the preceding figures; Fig. 'l is a section through my prel' rred form of circuit closer, taken on line 1 t of Fig. 5: Fig. 3 i a section taken on line I Trot Fig. and Fig. l is a perspective drtail view of the main shalt; with the circu t closing di ks thereon;

Hi designates the l'ramc work of a loom, ll the'main shalt. 12a counter sbat't geared tlnroto and having a crank 1 ll designate the lay ronncrled to the crank It, b conne ting rod l and n the lay mounted the shnttlernre HZ for the ghutllc 17. All tln-s'c part5 may be any ordinary or desir d tyre and torn: no part, oi my inveir lion.

i l nlltleel at (.Ult "In a pair of solenoid: l"

to the gluutlie-rare is i 5"Jleneiicl5 ol' each l possible in the d tails of pair being spaced apart Sutlioiently to permit of the ready exit and entrance between them of the shuttle 17. The. movable cores of each pair of solenoids is formed by the ends of a U-shaped bar 19, each end'ot' which is adapted to enter the pair of solenoids with the part 20 forming the base of the U in position to engage the end of a shuttle, as best shown inv Fig. 2, and forms the shuttle throwing elements. Each of these. shuttle throwing elements is normally held in its retracted-position by light coil springs 21. i

In order to close the circuits through the solenoids 18, without the ]n'oduction of any spark, as is very desirable, as sparks are very dangegous in a room where looms are Working, I provide a pair of circuit closers :22, one of which is connected to one pair of solenoids and the other to the other, and both preferably connected to a single battery 523, by the wire it. Each closer 22 comprises a cup or receptacle .24 mounted on a suitable support 25, said cup being adapted to-eontain oil or the like as indicated in Figs. 4 and 5.

26 is a pair of contact lingers, one mounted on each side of each cup :4, and to these fingers are connected the wires 24'.

ii--27 is arpair oi disks fast on the main hat't 11, one of which is adapted to extend into ea h cup it and extend between the contact. fingers it). 'lln-se disks are made of hard wood, rubber or other suitable material which is a non-conductor of ele tricity. Into an aperture cut in the body of each disk is inserted a block 2H of brass or other suitable metal which, during the rotation of the disk,

will pass between the cont-art lingers .36, thus closing the circuit through them. My hav ing the circuit closed in a bath ol oil all danger of sparks is eliminated.

In order to prevent the oil carried up by the disk 2T from spreading along the shaft; ll. l have provided a pair of disl's 25!, one lo ated on each side. of each disk '37 and spa ed therefrom, the disks 3 being of such a size that they will not contact with the sur'l'aee ot' the oil.

From the. foregoing descripti n of the con strurtion ot' the speoilic embodinn-nt of my invention whi h I have chosen to illustrate my invention it is believed that the operation will be apparent.

i am aware. that onsiderable variation is ronst-riu'tn n herein circuit shown and described, without departing from the spirit of my invention, and I do not intend to limit myself thereto, except as pointed out in the following claims, in which 'it is my intention to claim all the novelty inherent in the structure shown and described as broadly as the state of the art will permit.

Having thus described my invention what I claim as new and desire to secure byLetters Patent is:

1. In a loom the combination with a lay provided with a shuttle race and shuttle, of a solenoid located at each end of the race,-a core for the solenoid, a part carried by the core ahd adapted to engage the shuttle to throw the same, and circuit closers operated by the machine independently of the shuttle for controlling the solenoids.

2. In aloom the combination with a lay provided with a shuttle race and shuttle, of

a pair of solenoids spaced apart and located operated by the machine independently of the shuttle for controlling the solenoids.

In a-loom the combination with a lay provided with a shuttle race and shuttle, of I a solenoid located at each end of the race, a core for the solenoid, a part carried by. the core and adapted 'to engage the shuttle to throw the same, and circuit closers operated by the machine independently of the shuttle located in a bat-h whereby sparking is avoided for controlling the solenoids.

In testimony whereof I'aflix my signature in presence of two witnesses.
